C++, Java, SQL and tech interview questions problem solving prep & help

Coaching from the best technical interviewee out there on how to nail a technical interview with a big company. Give me core tips and tricks. Examples: 1. How many golf balls can fit in a school bus? 2. You are shrunk to the height of a nickel and your mass is proportionally reduced so as to maintain your original density. You are then thrown into an empty glass blender. The blades will start moving in 60 seconds. What do you do? 3. How much should you charge to wash all the windows in Seattle? 4. How would you find out if a machine’s stack grows up or down in memory? 5. Explain a database in three sentences to your eight-year-old nephew. 6. How many times a day does a clock’s hands overlap? 7. You have to get from point A to point B. You don’t know if you can get there. What would you do? 8. Imagine you have a closet full of shirts. It’s very hard to find a shirt. So what can you do to organize your shirts for easy retrieval? 9. Every man in a village of 100 married couples has cheated on his wife. Every wife in the village instantly knows when a man other than her husband has cheated, but does not know when her own husband has. The village has a law that does not allow for adultery. Any wife who can prove that her husband is unfaithful must kill him that very day. The women of the village would never disobey this law. One day, the queen of the village visits and announces that at least one husband has been unfaithful.
